This article mainly shares with you the method code of Linux to solve the PHP timer problem. PHP is often executed passively. The user sends an http request and the server executes it after receiving the request. It is difficult for him to take the initiative to do something. For languages like PHP that do not have timers or have very weak timers, Linux scheduled tasks should be used decisively.
The idea is to plan tasks, execute CURL commands according to the set time, or send http requests. Since you like to be passive in PHP, let you be passive to the end.
1. Create scheduled tasks
